. 8 Claims. 1

The present invention relates to phonographs and more particularly to record changers for automatically playing a plurality of records in a desired sequence.

Heretofore for use in homes phonograph record changers have been employed. but in order to make the structure simple and economical so as to reach a large portion of the public certain desirable features have not been incorporated in such changers. field a few record changers have been available which would play ten or twelve inch phonograph records intermixed. Such record changers, however, in the past have only played one side of each record, thus necessitating changing the stack of records if it were desired to play a symphonic album or the like consisting of a plurality of records. The simpler more economical phonograph record changers have generally limited the operation to playing only a stack of ten inch 1.

records or a stack of twelve inch records. Inthe one type of record changer, the records are slid off the turntable into a reject magazine. Such an arrangement has the disadvantage of producing additional surface wear onthe records due to the sliding action. Other phonograph record changers have been of the drop type, where the first record played dropped the maximum distance, thus placing an appreciable strain on the record particularly if the record wereslightly warped, as sometimeshappenseven thoughthe record is stored carefully in an album and a record cabinet.

It therefore becomes apparent that" there still is a need for an improved automatic record changer which will eliminate sliding and dropping and the resultant breakage or wear on phonograph records. Still it is'desired to provide a relatively economical record changer which will satisfactorily reproduce phonograph records of all types both standard and non-standard including records having any diameter eccentric groove.

It is therefore an object of the present invention to provide an improved automatic phonograph record changer which will play both ten inch and twelve inch records intermixed.

, It is still a further object of thepresent inventicn to provide an automatic record changer which will play the phonograph records in sequence on both sides.

Still another object of the present invention is to provide an improved automatic record changer which willplay the records in sequence on one side.

In the relatively high priced A further object of the present invention is to provide an improved automatic record changer which will play standard and non-standard records, warped records and records having any diameter eccentric groove.

Still another object of the present invention is to provide an improved automatic record changer which will eliminate sliding, dropping, and breaking of records.

Still another object of the present invention is to provide an improved automatic phonograph record player in which the records are easily stacked and removed.

Other and further objects of the present invention subsequently will become apparent by reference to the following description taken in connection with the accompanying drawings wherein:

The general appearance and assembly of the present invention is illustrated in Figure 1. This assembly include a mounting support or base 3| which may be provided at the corners by pins 32 surrounded by coiled springs 33. As

is customary the pins 32 are intended to fit into suitable apertures in other supporting structures in the cabinet which i to house the mechanism. The springs 33 support in a resilient manner the base 3|. Mounted on the base is a starting switch push button 34 and a control button 35. The control button is part of a mechanism which is reciprocable within the limits of an aperture 36 in an escutcheon 31. The control button or member is actuated in one direction to cause the phonograph to play one side of each record, and in the other direction to cause the phonograph to play both sides of each record in sequence. At the other end of the base or support plate 3| there is provided a record magazine or bin 38 in which a plurality of records 39 are stored so as to be played in sequence in the order stored by the automatic record changer mechanism. A record 4| is illustrated as being supported in a position preparatory to playing. The apparatu which supports the phonograph record is not entirely visible in this figure, but

' there is shown an arm 42 provided adjacent its upper extremity with a resilient extension 43 which carries a record engaging disk 44. The resilient extension portion 43 preferably is so resilient or flexible that a support stop 45 mounted on the arm 42 is provided to limit the deflection or movement of the member 43 and 44. The record has just been elevated to proper position by a record elevator trough 46 positioned directly beneath the record 4|. A dual pickup arm assembly 41 is shown in a position just prior to the orientation of the styli of the pickup cartridges of the arm with respect to the outer periphery of the record 4|.

After the phonograph record has been played, the arm 42 moves forwardly to carry with it the phonograph record 4| for a short distance. The phonograph record 4| thereupon engages the record removing structure 48 which may be in the form of an inverted U-shaped structure mounted upon the base 3|. The record carried to the limit of the removing member 48 is then positioned directly above the return runway or record trough 49 down which the record rolls to the reject record bin or magazine 5|. The bin 5| is shown as having therein a plurality of played or rejected records 52 which are supported by an upwardly extending inclined side portion 53 and another portion 54 extending at right angles to the portion 53 so as to engage a portion of the periphery of the rejected records. To supply a new record for subsequent playing there is provided a selector mechanism 55 which is adapted to remove the records one at a time from the storage bin or magazine 38 at the beginning of each cycle of operation. This mechanism will subsequently be described in detail since it is shown-in Figures 5 and 6. The record selected by the mechanism 55 eventually rolls down a record guide or trough 56 which is positioned so that a record will continue on to the .record elevating trough 46. The elevator trough 45 is raised in an amount depending upon the diameter of the phonograph record to be played. It may be assumed that in Figure 1 all of the records are of the maximum diameter or are twelve inch records. A twelve inch record extends beyond the record trough 45 a distance suflicient to engage an index member 57 which is engaged only by the twelve inch record to control apparatus subsequently to be described so that the trough 46 is elevated a lesser amount than is the case with a ten inch record.

Further details of the structure shown in Figure 1 will be appreciated by a consideration of Figures 2, 3, and 4. The record magazine or bin 38 at one end is provided with an aperture 56 so that a lever arm 59 may move therein. The lever arm 59 is pivotally supported at 6| by a suitable balancing structure mounted on the panel or base 3|. The outer extremity of the lever arm 59 extends to the proximity of the center of the longitudinal dimension of the record magazine 38. The outer extremity of the arm 59 has an upwardly extending arm portion 62 which carries a half round strip 63. The half round strip 63 preferably is formed of resilient material such as rubber for example so that this member bears against the center of the records which are stored in the magazine 38. The arm 59 is spring biased by a spring 6|] so as to urge the upwardly extending portion 62 and the half round member 63 carried thereby against the records so that as the records are removed one at a time by the selector mechanism 55, the records are urged forwardly against the forward wall 64 of the record magazine 38. The forward wall is provided at each end with suitable upwardly extending fingers or projections 65 and 66 which serve to retain the records in the magazine 38 until removed therefrom by the mechanism 55.

I The records are removed from the magazine 38 one at a time by the mechanism 55 the details of which wil1 subsequently be described in connection with Figures 5 and 6. The mechanism 55 is actuated by a bell crank 61 pivotally mounted on the underside of the base 3|. The bell crank 6! is biased toward one position by a suitable spring 68 having one end secured to a suitable portion of the base 3|. The bell crank 61 is connected to a reciprocable rod 69 suitably supported by guide members H and 12. The reciprocable rod 69 is actuated by a cam 13 mounted on a sequence operation cam shaft 14.

This cam shaft 14 carries a gear 15. which is engaged by a worm gear 16 mounted on. the shaft of a sequence operation motor- 1.1.

The sequence operation cam shaft 1.4 carries a number of other cams such as the cam 18 which during a portion of the revolution of the shaft 14 engages the lower extremity of the record engaging arm 42 which is pivotally supported by a plurality of spindles 19. The arm is normally biased outwardly by suitable spring means. such as the spring 9| which may have one extremity secured to a stationary point such as a point, on the base 3 I. The cam shaft 14 also carries a cam 82 which engages a camfollower 83 forming a portion of the record elevator mechanism 84. This mechanism will subsequently be described in detail when reference is made to Figure 12. The shaft 14 also carries a cam 85 with a cooperating cam surface 86. The cam surfaces85 and 89 are adapted to engage forwardly extending portions of a plurality of levers 81 and 88 having upwardly extending extremities and arranged for engagement by a lever 89. The lever- 89 is secured to the dual pickup arm assembly 41. The levers 81 and 88 are of difierent lengths so as to position the pickup arm assembly 41 at different positions dependent upon the diameter of the phonograph record to be reproduced. The arm 81 is provided with a downwardly extending portion 9I which is adapted to be engaged by the pins 92 and 93 carried by cams Hand 95. The cam 95 is pivotally mounted with respect to the cam 99, as will subsequently be explained in connection with Figure 10. The upwardlyextending levers 81 and 88 are pivotally mounted within a certain amount of friction on a suitable support rod 98. The lever 81 is set during each half cycle of operation of the cam shaft 14 by the operation of the pins 92 and 93. The lever 88 is set only when the record index member 51 is actuated by a twelve inch record. Actuation of the member 51 by a twelve inch record moves themember 51 from the solid line position shown in Figure 3 to the dotted line position so-thatthe lower extremity of the rod 91 forming a portion of the assembly 51 engages theupwardly extendingarm 99 to move that arm intoa position where-subsequently the arm 89 will engage the upper extremity of the lever 88.

Prior to the time that either of the arms 81 or 88 is engaged by the lever arm- 89 which attached to the pickup arm assembly 41, the cam 94 or the cam 93 raises the leverarm 89 This upward movement of the lever arm 89 moves the pickup arm assembly 41 outwardly so as: to be positioned beyond the outer periphery of the larger size record to be played. Thereafter the arm 89 is lowered until it reaches either one of the stops 81 or 88. The stop 81 is moved into position each half cycle of the operation of the sequence cam shaft 14 so that the pickup arm assembly 41 will be properly positioned with respect to the smaller of the records'to be played. If the member 51 has been actuated by a twelve inch record, the leverarm 88 is movedinto position so as to position the pickup arm assembly 41 at the outer groove of the larger phonograph record. The arm 89 and the pickup arm assembly 91 are dynamically balanced so that it is necessary to apply a force to the arm 89 to move the arm downwardly to engage either the levers 81 or 99. After either the cam 94 or the cam 95 has raised the lever arm 89, the cam subsequently engages a spring member 98 secured to the underside of the arm 89' to move the arm down- 6 wardly. The member 98 is formed of resilient material so as to-permit the cam to. move past this member after the outer extremity of the arm 89 has been stopped in its downward motion by either of the levers 81 or 88.

The operation of the levers 81 and 88 and the cams 94 and 95 will be better understood by reference to Figures 10 and 11 from which it. will be seen that the lever 89 is pivotallymounted at 99 on a sleeve member I9I mounted on the shaft 96. The arm 89 is biased to its upright position by suitable spring means such as a leaf spring I92. The arm 88 is pivotally mounted so that during one portion of one half of the revolution of the cam shaft 14 the arm is swung out of the path of the lever arm 89. This is accomplished by the cam 89 which at the same time restores the lever arm 91 to its original position. The lever arm 81 being restored to its original position therefore no longer limits the downward movement of the lever arm 99. The angular displacement of the rod 88 from the path of the arm 89 no longer limits its downward movement, and hence during the reproduction of the phonograph record the arm may move downwardly until the stylus of the pickup arm 41 reaches the eccentric circle at the inside of the record. After the time for playing the second side of the phonograph record has passed, the cam shaft 14 rotates the cam surface against the forwardly projecting arms of the levers 81 and 88 to restore these arms to their original position so that they may be actuated to new positions in accordance with the next record to be played.

The cam is pivotally connected to the structure which supports the cam 94 by a pair of pivots i93. The cam 95 is so constructed as may be seen in Figure 11 that it may be displaced to or in the direction of the dotted line representation shown. This is brought about by the engagement of the shifting cam surface I94 which is adapted tobe engaged by a lever I95 shown in Figure 4. Sub sequent to engagement with the lever I95 the cam 95 is restored to its original position by a spring I99. The lever I95 shown in Figure 4 is an upwardly curved projecting arm of a bell crank lever H91 pivotally,mounted at I98. One extremity of the bell crank I91 is connected to a longitudinal link I99 which is pivotally connected to the downwardly depending portion I II of the push button 35. The bell crank I91 at an intermediate point is provided with an upright finger or member I I2 which may have a certain degree of resiliency and which is intended to engage one side of a shiftable cam II3, the purpose of which subsequently will become apparent. The slidebutton 35 when actuated to the position shown in Figure 4 moves the bell crank I91 so that the member H2 is in engagement with the shiftable cam member I 33. At the same time the outwardly extending curved arm I95 is projected into the path of the cam 95 so asto defiect this cam out of the path of the lever 99.

The mechanism 55 for supplying phonograph records one at a time from the record magazine 98 to the record track 59 and to the record elevator trough 45 is shown in detail in Figures 5 and 6. The apparatus 55 is mounted on an inclined support H4 which extends through the mounting base 3i and which terminates at the record magazine 38 in the proximity of the projection 95. The support II4 adjacent its lower end carries a reciprocable member III-5 which is connected to the bell crank 61 shown in Figure 4. The member H9 is connected toapivoted member II! which is biased to an upright position by a suitable spring H8. The member H1 is arranged for limited pivotal movement in a counterclockwise direction as seen in Figure 6. The member I I! is provided with a groove or passageway I I9 for cooperation with a pin I2I which is fixedly secured to the inclined support II 4. The member I I! also carries a resilient or spring member I22 having an inwardly turned upper end I23 which extends toward the inclined support H4 sufficiently so as to normally block the upper end of the groove or passage H9. The member I I! adjacent its upper end carries a relatively thin support plate I24 to which is secured by means of a rivet I25 a backing plate I26. The backing plate I26 adjacent its lower end carries an elongated member I21 having a forwardly projecting step I28 which is arranged to engage the underside of an edge of a phonograph record. The member I26 adjacent its upper extremity carries a friction pad I29 which may as shown have a circular configuration and which is adapted to engage frictionally one side of a phonograph record. In operation the cam shaft I4 rotates the cam I3 shown in Figure 4 to reciprocate the rod 69 and actuate the bell crank 61 against the action of the spring 68. This pushes upwardly the lower member H6 which elevates the member I IT. The member III carries the spring I22 which then encounters the pin I2I, causing the member II I to be deflected in a counterclockwise direction. This positions the step I23 beneath the edge of a phonograph record, and the friction pad I29 against one face of the record. The member I I6 continues its upward motion so as to raise the members I2! and I29 to the dotted line representation shown in Figures and 6, which then will cause the record to be lifted above the projection 65 on the magazine 38. At the upper limit of the movement of the member H6, the pin I2I will be positioned opposite the lower entrance to the groove H9. When this occurs the spring I I8 shifts the member I I! in a clockwise direction somewhat beyond the position shown in solid lines in Figure 6. When this occurs the phonograph record is released into the record trough 56 from whence it rolls down on to the elevator trough 46. The reciprocable member H6 begins its return motion so that the pin I2I relative to the groove H9 moves upwardly and eventually encounters the underside of the turned-in portion of the spring I23. Further return of the member H6 causes the pin I2I to deflect the spring I 23 so that the pin eventually reaches the upper extremity of the groove H9 and becomes positioned relative to the groove and the member I IT as shown in Figure 6. When this occurs the cam I3 is moved to a dwell position but the mechanism is in readiness for actuation to supply a new record when the previous record has been reproduced and moved into the reject magazine 5 I.

When the phonograph record is supplied by the mechanism 55 heretofore described, the record goes down the trough 56 into the elevator trough 46. If the record is of the larger diameter as is the case with the twelve-inch record, the record will engage the member 57 shown in Figure 12. The member 51 is mounted for limited reciprocable movement by suitable support means such as the sleeve I3 I. When the member 5'! is moved, a projection I32 is secured to the rod 91 which is positioned above an outwardly extending projection I33 mounted on the inner sleeve I34 of the outer extremity I44. The outer extremity record elevator mechanism 84. The inner sleeve I34 is mounted within a suitable bearing sleeve or support I35 secured to the mounting base 3|. The sleeve I34 has alower aperture equal to the diameter of the push rod 83. The sleeve I34 has a larger inner diameter so as to accommodate a coiled spring I36 extending between the lower extremity of the sleeve I34 and the upper extremity of the push rod 83. While the spring I36 is for purposes of illustration described as being contained within the sleeve I 34 and secured in a particular manner, it is intended that this illustrate the manner of operation since it is desired to have a certain degree of freedom of motion between the member 83 and the member I34. The cam 82 continues to rotate in a counterclockwise direction. This elevates the push rod 83 Which acts against the spring I36 to lift the sleeve I34 until the projection I33 strikes the projection I32 of the rod 9'1. At this point the upward movement of the trough 46 ceases. Further movement of the push rod 83 merely flexes the spring I36. If the spring is mounted in the manner described the spring merely stretches during this operation. It of course will be appreciated that if desired a compressible spring might be used to interconnect the push rod 83 and the inner sleeve I34.

If the member 57 shown in Figure 12 is not actuated, as is the case When a ten-inch record is brought into position for playing, the elevator trough 46 rises to a higher level since there is no stop in the path of the projection I33 mounted on the side of the inner sleeve I34. Thus the smaller diameter record is elevated to a greater extent than is the larger diameter record.

When the elevator trough 46 has reached its proper height the cam 78 is moved to a position where the lower extremity of the arm 42 is engaged, thus pivoting the arm against the action of the spring 8| to move the upper extremity outwardly. This occurs just prior to the time that the record enters the trough 46. Thereafter the cam continues to mOVe on until the lower extremity of the arm 42 has been released, whereupon the spring 8I pushes the lower extremity so as to cause the upper extremity to be moved inwardly. The upper extremity of the arm 42 carries the resilient member 43 which may be secured to the arm by any suitable means including an imbedded support button I31. Within the member 43 there is mounted a bearing member I38 which carries a shaft I39. The shaft I39 is provided with an annular groove I4I into which may be positioned a limiting set screw I42 to prevent the shaft from leaving the bearing I38. The lower extremity of the shaft I39 and the recess of the bearing I36 are provided with conical surfaces sufficient to accommodate an end thrust ball bearing I43. The shaft I39 carries the record engaging disk 44. The shaft I39 has a tapered I44 is adapted to pass through an opening I45 in the phonograph record 4| and into a recess I46 in a shaft I47. The shaft I4? is mounted in a bearing member I48 secured to an upright support I49 which is carried by the support base 3|. The shaft I41 at one extremity is secured to a record engaging disk or plate I5I. The other end of the shaft I4! is connected to a driving wheel I52. It will be noted that the shaft I4! extends beyond the wheel I52 so that this shaft may be provided with a suitable upright wheel to insure a relatively constant speed of rotation of the disk I5I and the phonograph record 4 I.

As maybe seen from Figures '7 and 9 the wheel I52 has an outer periphery of a friction material I53 of rubber or the like. The wheel I52 is engaged by one of a plurality of drive shafts I54 and I55 which are connected respectively to wheels I56 and I57. Each of these wheels is also provided with an outer periphery of a high friction material such as rubber. The wheels I55 and I57 are mounted on shafts I55 and I55 extending through a support plate I59 having a downwardly extending projection II connected to a spring I62 one end of which is connected to a mounting support I49. A rod IE3 is connected to the plate I59 so that the rod may place either of the wheel I54 and I55 in engagement with the wheel I52. The outer peripheries of the wheels I56 and I57 are in alignment so that the wheel I55 drives the wheel I57. The wheel I56 is driven by a wheel I64 mounted upon a shaft I55. The shaft IE5 is driven by a motor I65. When the wheel I54 is in engagement with the wheel I52 the phonograph record is rotated in one direction, and when the other wheel I55 is in engagement with the wheel I52, the phonograph record 44 is rotated in the opposite direction.

The lever I63 connected to the plate I59 extends downwardly through the mounting base 3! as shown in Figure 4c. The lower extremity of the rod IE3 is bent at right angles to engage a slot I57 in the upright portion of a reciprocable slide I58. Preferably the connection between the end of the rod I63 and the slot I67 is formed with a certain degree of freedom to permit a small limited movement of the slide I63 without affecting the position of the rod I63. The rod I53 at one extremity carries the pivoted cam member II3. This same extremity of the slide I68 has an upwardly extending arm I59 which engages a slot in a bell crank I7I. The bell crank is biased to a certain position by a spring I72. The bell crank I7I at the extremity of the other arm is provided with divergent portions I73 adapted to engage the push rod of a switch I74. The bell crank I7I is secured to a rod or shaft I75 which supports the pickup arm assembly 47.

Reference may now be made to Figures 13, 14, 15, which illustrate the manner in which the pickup arm assembly is supported. Figure 13 shows the bell crank I7I mounted on the shaft or rod I75 which is supported by suitable brackets I76 secured to the underside of the mounting plate 3|. The shaft I75 is composed of two sections interconnected by a U-shaped channel member I77. of its sides is provided with a pair of elongated slots I78 which receive a plurality of pins I75; The pins I75 are carried by a mounting block IBI which has transversely extending shafts I82 upon which the pickup arm assembly is pivotally supported. The block Isl is provided with trunnions I83 extending into the two portions of the shaft I75 as may be seen from Figure 15. R0- tation on the shaft I75 by the bell crank I7I displaces the pickup arm assembly 47 in one direction or the other in order to engage a pickup stylus with a surface of a phonograph record M. In Figure 14 the pickup arm assembly 47 has been tipped in a counterclockwise direction for the reproduction of one side of a phonograph record. The pickup arm assembly 47 together with its actuating lever 89 is statically balanced by a counterweight I84, the position of which may be adjusted by screw means I85. After the bell crank I7I has moved the tone arm or phonograph The channel member I77 in each pick-up to one side of the record or the other, the slots I73 carrying the pins I79 permit a certain degree of freedom between the pickup arm assembly 47 and the position as determined by the shaft I75 to accommodate phonograph records of different thickness and to permit limited movement of the pickup arm assembly 47 during reproduction due to slight unevenness of the phonograph record. The pivots I82 upon which the pickup arm assembly 47 rests permit the arm 59 to move the pickup arm extremities in and out relative to the outer periphery of the phonograph record, and also permit the phonograph pick-up stylus to follow the groove in the record during reproduction.

The slide I58 carries the pivoted cam H3. When operation of a phonograph is to be initiated the push button 34 is depressed. This push button acts upon a rod I35 having a transversely extending arm G87 arranged to engage electric switches $88 and I95. The switch its permits manual playing of individual records. The rod I35 engages one end of a lever I89 secured to a shaft I2! mounted in a bearing I92. The other end of the shaft I9! carries a resilient finger 553 adapted to be moved into engagement with the pivoted cam II3 whenever the push button 34 is actuated. This shifts the cam I IS in a counter clockwise direction so that upon initiation of op-- eration of the phonograph the phonograph will begin playing a certain side of the phonograph record. The resilient finger I93 therefore moves the cam H3 to the position shown in Figure 16. The cam 5:3 as seen in Figure 16 engages the left surface of the cam H3. The cam 94 moves on downwardly against the cam surface, thus completing a reciprocable movement toward the right of the slide I53. This movement actuates the rod I 53 upwardly so as to move the plate I58 of Figure 7 to bring the wheel I55 into engagement with the wheel I52. The upward movement of the rod I53 causes the spring I62 to be depressed as the extremity I ii passes over dead center, thereby insuring positive engagement of the wheel 555 with the wheel I52 in spite of the fact that a certain amount of freedom is permitted between the slot I67 of the slide I68 and the rod 53.

As the cam 54 continues on down the left face of the pivoted cam IE3, this cam is tilted to the opposite position shown in Figure 17. The cam I I3 has a certain degree of freedom between two limits represented by the limit stops I94. When the cam reaches a position approximately that shown in Figure 17, the cam shaft 74 is stopped since at this time the actuation of the slide IE3 has caused the arm I59 to move the bell crank ill. The divergent fingers I73 of the bell crank are arranged to engage the switch I75 which is so connected in an electrical circuit shown in Figure 25 to bring about interruption of the current supply for the sequence operation motor 77. The phonograph pick-up arm moves on to reproduce the phonograph record, and when the eccentric circle at the inside of the record is reached by the pickup stylus, the arm 8%? secured to the tone arm 47 is moved to engage an electric switch 55 which again causes current to be sup plied to the electric motor 77. The cam 94 then continues on from the position shown in Figure 17 to give a slight movement to the slide 55 8. Subsequent to this slight motion of the slide I55 the spring 572 acting on the bell crank I7! will cause the pick-up arm assembly it to be restored to a neutral posi i n 50 that when the cam 95 or the cam 95 next engages the outer extremity of the lever 89, the extremities of phonograph pick-up arm I1 may be moved outwardly away from the record. It may be assumed that both sides of the phonograph record are to be played, whereupon the cam 95 will engage the right side of the pivoted cam I I3 in a manner illustrated in Figure 16. The cam 95 continues on down to the position generally indicated in Figure 19 to move the slide I68 to the left, thus causing the rod I63 to be pulled downwardly. The downward motion of the rod I63 causes a compression of the spring I62 and a shift of the plate I 59 so that the new position assumed by the plate I59 will be that shown in Figure 7 This shift in the plate I51 brings into engagement the wheel I with the wheel I52, thus reversing the direction of rotation of the phonograph engaging plate I5I The cam 95 eventually leaves the cam surface H3 with the cam I I3 in the position shown in Figure 19, which it will be noted corresponds to the position of the cam shown in Figure 16. Thus when the cam 94 reaches the cam surface I I 3 for the reproduction of a, subsequent record, the extremities of the pickup arm -91 will again be displaced first to a side of the record corresponding to the first side originally played on the first record by the phonograph.

If it is desired to cause the phonograph to play only one side of each record the slide 35 is moved to the position shown in Figure 4 so that the resilient upright finger I I2 constantly bears against the cam II3. Under such operation the cam 94 will pass through the stages shown in Figures 16 and 17 and as soon as the cam 94 has cleared the cam II3, the resilient finger II2 will restore the cam II3 to the position shown in Figure 16. When the cam 95 moves toward the position where the cam would engage the cam surface II3, the cam surface I04 carried by the cam 95 engages the curved finger I05 extending from the bell crank I01 which deflects the cam 95 so that the cam never engages the pivot-ed cam surface I I3. This causes the cam shaft 94 to continue to rotate so that the cam surface 18 engages the lower extremity of the arm 42 to withdraw the phonograph record from engagement with the driving plate I5I. The arm 42 continues to move outwardly due to the action of the spring 8| until the phonograph record is engaged by the removable apparatus or U-shaped arm 48 which strips the record 4| from the projecting spindle I44 so that the record engages the runway 49 and travels on to the reject magazine 5 I.

The electrical circuit diagram for the phonograph is shown in Figure 20. A pair of conductors I96 are arranged to be connected to a suitable source of alternating current. One of the conductors leads to a manually operable switch I91 by means of which all power to the phonograph may be controlled. In order to initiate operation of the phonograph, the switch I91 is closed so that current may be supplied to the phonograph motor I66 by way of the conductor I98 connected to one contact of a pair of switch contacts I99. The pair of switch contacts I99 are controlled by the cam 13. The conductor I98 also is connected to one of a pair of contacts 20I which form a switch located adjacent the front edge of the record magazine 39. As long as any record remains in this magazine the switch 20I is closed, but when the last record has been removed, the switch will open. Current from the switch contacts I99 and NI is supplied by the conductor 202 to one side of the phonograph record turning motor I66. The return conductor 203 of the motor I66 is connected to one of the pair of conductors I96. A control circuit is provided for the motor 11 which operates the sequence operation shaft. One side of the motor is connected to the alternating current line conductor I96. Another conductor extends from the motor 11 to the switch contacts of an alternating current relay 204. A plurality of switches I14, I88 and I 95 are arranged in a circuit for controlling the energization of the coil of the relay 204. The switch I16 is a normally closed switch which when actuated merely interrupts the circuit momentarily. The switch I88 is a normally open switch which is closed by actuation of the push button 39. The switch I95 is also a normally open switch which is actuated by the arm 89 of the tone arm whenever one side of a phonograph record has been reproduced. The two switches I95 and I68 are connected in parallel between the coil of the relay 204 and the normally closed switch I14. The normally closed switch I14 is connected to the conductor 202.

After the switch I91 has been closed, the push button switch 34 is actuated to momentarily close the normally open contact switch I88, which therefore permits current to be supplied to energize the coil of the relay 204 which closes its contacts. Closing the contacts of relay 204 looks the relay 204 in circuit and at the same time suppliespower to the sequence operation motor 11. This motor continues to operate until the extremities of the pickup arm assembly 41 are moved into position with a pickup stylus in contact with one side of the phonograph record, whereupon the bell crank "I with its divergent arms I13 is moved to actuate the switch I14. Actuation of the switch I14 momentarily interrupts the flow of current through the relay 204 which opens thus stopping the operation of the motor 11. The pickup stylus moves toward the inside of the phonograph record and when the eccentric groove or circle is reached the lever 89 actuates the switch I95 thereby again completing a circuit through the energizing coil in the relay 204 which again locks itself into position. Assuming that another side of the record is to be played, the extremities of the pickup arm assembly 41 are moved to neutral position and then moved to the other side of the record whereupon again the divergent arms I13 actuate the switch I14 to momentarily interrupt the circuit and stop the operation of the sequence operation motor 11. Thus both sides of the phonograph record are reproduced. Where only one side of the phonograph record is to be reproduced, the

switch I14 is actuated only once for each phonograph record. When all of the phonograph records in the record chamber or magazine 38 have been removed, the switch 20I is opened thus preparing a circuit which subsequently will stop all operation of the phonograph. The switch 20I is in closed circuit relation and in parallel to the switch I99 so that as long as phonograph records are still to be played, the periodic actuation of the switch I99 by the cam 13 will not interrupt the circuit. After the last phonograph record has been reproduced the switch 20I is open and the cam 13 moves to a position where it opens the switch contacts I 99, thereby interrupting the circuit to both electric motors 11 and I66. The phonograph cannot be actuated until more records are placed into the record magazine 39, or the switch I is closed.

It has been stated that the switch I14 is of the type which is normally closed and which only momentarily interrupts the circuit when actuated. Any suitable type of switch may be used for this purpose and one type of switch is illustrated in Figures 21 and 22. The switch I'M has an actuating rod 265 which is biased outwardly by a spring member 2%. The rod 295 carries a curved spring 201 which is adapted to engage a contact arm 238. The contact arm 208 carries a contact 2518 which normally is in engagement with a fixed contact 2| i. When the rod 295 is actuated the upper extremity of the spring 201 pushes against the contact arm Ztil to move it to the dotted line position shown in Figure 22. As the rod 2115 continues to be positioned inwardly the end of the contact arm 208 moves past the forward extremity of the spring actuator Zill to return to the solid line position shown in Figure 22. Subsequently the pickup arm assembly 41 is returned to neutral position thus releasing the push rod 265 which is restored to its original position by -a spring 268. In the restoring movement the upper end of the spring actuator 2531 deflects inpassing over the outer extremity of the switch contact arm 2% since that arm will not move as its contact 209 is in engagement with the fixed contact 2| i.

While Figures 5 and 6 have shown one manner of transferring phonograph records one at a time from the record magazine 38 to the record trough or track 56, other means may be employed. Another suitable means for supplying the phonograph records one at a time to the trough as is illustrated in Figures 24, 25, and 26. The cam shaft M carries the cam i3 which acts displaced from an actuating rod of the mechanism of Figures 5 and 6, the cam i3 is correspondingly displaced on the shaft M. The rod 212 is supported and guided by a guide member 2l3 secured to an inclined plate 2 i4 extending through the mounting base 3!. The plate 2 extends. outwardly to the proximity of the upwardly extending record retaining finger or ear 66 of the record magazine 38. The rod 2!?! adjacent its upper extremity carries a pivoted rod 215 biased by a Spring 2 it so as to urge the upper extremity of the rod 2V5 toward the records in the magazine 38. The rod 2 l 5 adjacent its upper extremity carries a pin 2|! arranged for operation in a generally V-shaped groove 2th. The groove H8 1 is formed in the upper portion of a support member 2M. The side of the record magazine 38 adiacent the upwardly extending finger portions 65 is inclined downwardly to conform generally to the upper edge of the groove 2H8. This permits the foremost record to drop down slightly as indicated in Figure 24. At the bottom of the groove 2 l 8 there is a downwardly or vertically extending groove portion 219. In Figures 24 and 25 the cam 13 is just approaching the position where the rod 212 is to be moved upwardly. A partial upward movement has taken place so that the pin 2 i! is about to enter the right hand portion of the vgroove 218. The pin 2i'l'wil1 follow the groove 2 i t as the rod 2 l 2 moves upwardly until the upper edge of the rod 2l5 engages the underside of the foremost phonograph record. The weight of the record upon the upper end of the rod 2!? is sumcient to prevent the spring Zit from further defleeting the arm H5 in a clockwise direction as seen in Figure 24. The rod 2E2 continues upwardly until the cam 73 has reached its maximum position. At this point the phonograph record is moved upwardly sufficient so as to clear the projection 66 on the record magazine 38.

lhis raising of the phonograph record as would be seen from Figure 25 produces a lifting or rtation -of therecord in a counterclockwise direction. The record having cleared the upward projection '66 of the magazine 38 thereupon drops into the record trough 55 and rolls on down to the record elevator trough shown in Figures 2 and e. The-cam l3 continues on to permit the rod 212 to return. As the record was supplied to the record trough B, the succeeding records were moved forwardly so that when the record left the upper. extremity of the rod 2I5, the rod Was maintained in a generally horizontal position by the next sucagainst a rod 2E2. Since the rod 2 I2 is angularly I record magazine ceeding record. The rod 2l2 in moving downwardly then causes the pin 2!! to engage the left hand leg of the V-trough 218 as seen in Figure 24. The pin 2-H continues on down into the vertical groove 219 where it remains until the cam 13 again brings about an upward movement of the rod 2 #2.

From the foregoing it will be seen that there again has been provided an arrangement for supplying the records one at a tim to the record elevating mechanism and that this apparatus is actuated in accordance with the sequence operation mechanism of which the cam shaft '14 is a part.

Operation The invention will more readily be understood by assuming a certain operation for an automatic phonograph. First it will be assumed that the operator selects a number of twelve-inch phonograph records which are to be placed in the The operator deflects the arm 69 having the upright extension 62 and places the phonograph records in order in the bin 38. The arm 59 is then permitted to bear against the records and to support them. The curved half round strip 63 engages the records at about their central point, thus urging the records forwardly against the record stops 65 and 66. The operator then determines whether one side or both sides of the records are to be played in sequence. It may first be assumed that both sides of the records are to be played whereupon the operator checks to see that the push button 35 which operates in the aperture 36 of the escutcheo'n 31 is moved to the right as far as possible. Thereafter the operator may close the main power switch 151 of Figure 20. The push button 33 is then actuated which causes the extension lever I81 to strike the push rod of the switch lfsl.

The switch I85 having been closed by the action of the push button 34 completes an electrical circuit through the relay 2:14 which attracts its armature and locks itself in circuit. The closing, of the relay 2134 brings about energization of the record sequence operation motor "if. The closing of the switch i9! completed the circuit to the record driving motor I56 through the record switch 2'!!! which is held closed as long as a record remains in the record magazine 38.

The sequence operation motor H by means of the gears 15 and it drives the cam shaft E i. This cam shaft is provided with a plurality of cams which in their proper relation are diagrammatically indicated in Figure 23. This diagrammatic representation in Figure 23 has been given since otherwise it is difficult to determine from the perspective views and the broken away figures the exact preferred relationship between the various cam members on the cam shaft. The initial actuation of the push button 3 3 causes the rod I35 to engage the lever his to rotate the shaft ;5 '19! supported in the bearing 32. The shaft i9! at its other extremity carries a resilient finger I93 which is moved against the pivot cam II3 supported at one end of the slide I68. The momentary action of the resilient finger I93 against the pivot cam II3 positions the cam so that the operation of the phonograph will begin with the playing of the particular side of the first record. The cam 13 begins to rotate, the cam 18 already being in engagement with the lower extremity of the arm 42 since the last played record prior to the restoration of the record to the reject bin 5I brought about an operation where the arm 42 withdrew the record from the driving disk or wheel I 5|. The arm 42 already being engaged by the cam 18 remains pivoted outwardly so that when a record is supplied, the arm 12 is moved outwardly in readiness to accept the record. The first action occurring as a result of the rotation of the cam shaft 14 is the movement of the cam 13 against the push rod 69. The rod 69, supported in bearing members H and 12 shown in Figure 3, actuates the bell crank 61 against the action of the spring 68. The bell crank 61 moves upwardly the rod IIB thus actuating the record selecting mechanism 55.

The record selecting mechanism 55 which withdraws the records one at a time from the record magazine 38 is shown with particularity in Figures 5 and 6, the various parts of which have previously been described. The upward movement of the rod H5 causes the record engaging pad I29 to be moved upwardly and toward the first record. The step portion I28 of the member I21 engages the underside of the outwardly extending portion of the record as is apparent from Figures 5 and 6. At about the limit of the upward movement the record has been raised sufficiently so that it clears the record retaining ear 65 of the record magazine 38. The record thereupon slides into the trough 56 whereupon it disengages itself from the record retaining car 66. The record thereupon rolls down the trough 58 and comes to rest in the record elevating trough 46. Since the record in the trough 46 is a twelve-inch record, the outer periphery engages the record index arm 51. The displacement of the arm 51 by the twelve-inch record brings the projection I32 immediately above an outwardly extending projection I33 on the sleeve !34 of the record elevating mechanism as seen in Figure 12. The lower extremity of the rod 91 as is apparent from Figure engages the pivoted lever arm 88 supported on the shaft 95. Thus the rod 88 is moved to a vertical position so as to constitute a limit stop for the arm 89 Which is secured to the dual pickup arm assembly 41. The cam 82 on the cam shaft 14 engages the cam follower 83 which is connected by a spring I36 to the record elevating trough 48. The trough 46 is raised to a limit determined by the cooperating stops I32 and I33. At the time that this upward limit is reached, the cam 18 goes off over the lower extremity of the arm 42.

The disengaging of the cam 18 with the lower extremity of the arm 42 permits the centering pin I44 to engage the aperture I45 in the phonograph record 4!. The pin I44 moves on into the aperture I46 in the shaft I41 until the relationship of the parts is like that shown in Figure 9. The spring 82 acting against the lower extremity of the arm 42 places a suificient bias against the upper extremity of the arm 42 so that the phonograph record M is firmly engaged between the driving plate I 5| and the disk I38 supported rotatably from the arm 42. The resilient mounting 43, which carries the shaft I39, the centering pin I44 and the record disk 44, firmly engages the phonograph record 4| irrespective of differences in thicknesses between the records supplied. The resilient structure 43 accommodates any axial displacement between the axes of the shaft I46 and the shaft I39.

The cam shaft 14 continues to rotate thus bringing the cam 94 into further engagement with the arm 89 secured to the pickup arm assembly 41. At the beginning of the operation of the sequence operation motor 11, the cam 94 is positioned so as to be in engagement with the outer extremity of the arm 89 since the extremities of the pickup arm assembly 41 were restored to a position beyond the outer extremity of the phonograph record prior to the time that the last phonograph record in the previous cycle of operation had been removed from the arm 42. The cam 94 therefore continues for a short time to act against the arm 89, whereupon it leaves the arm to engage the resilient spring 93. The spring 98 being engaged by the cam 94 moves the tone arms 41 inwardly so that the styli are in the proximity of the outer periphery of the phonograph record. The amount of movement of the extremities of the pickup arm assembly 41 is determined by the upright limit stop 88 which it will be recalled had been moved into position by the engagement of the index member 51 with the outer periphery of the twelve-inch record. The arm 89 therefore moves downwardly by the action of the cam 94 on the spring 98 until the arm 89 is stopped by the upwardly extending arm or limit stop 88. Thus the extremities of the pickup arm assembly 41 are arranged so that the pickup styli are located in the proximity of the outer groove of the phonograph record.

After the extremities of the pickup arm assembly 41 have been positioned as described the cam 94 leaves the spring 98 and continues on to engage the pivoted cam surface II3 as shown in Figures 16 and 1'7. The cam 94 moves on downwardly along the left side of the pivoted cam I I3 thus bringing about a movement toward the right of the transversely arranged slide I68. This movement of the slide I68 produces an upward movement of the rod I63 which as is apparent from Figure 7 causes the wheel I55 to be placed in engagement with the driving wheel I52. Thus the movement of the slide I88 determines the direction of the rotation of the phonograph record driving disk I5I. The movement of the slide I68 also brought about movement of the bell crank I1I due to the interconnection of the bell crank with the slide through the upright extending arm I69. The movement of the bell crank I1I brings about a rotation of the shaft I15 which as is apparent from Figure 13 supports the pickup arm assembly 41. Thus the assembly 41 is moved to the position shown in Figure 14.

At the same time the action of the bell crank I1I is such that the divergent extremities I13 engage the switch I14. The closure of the switch I14 which is constructed in the manner illustrated in Figures 21 and 22 momentarily interrupts the circuit through the relay 284. The relay 284 therefore opens its contacts and interrupts the flow of energy to the sequence operation motor 11 thereby bringing about a cessation of the motion of the sequence operation cam shaft. Each stylus follows the grooves of the record until the one side of the phonograph record has been played and the stylus reaches the concentric circle of the record.

While the cam 94 is moving from the spring 98 on the lever- 89 and into engagement with the pivoted cam II3. the cam 86 is brought into engagement with the horizontal extension of the limit stop 88 thereby deflecting. the stop 88 out of the, path of the. arm 89. Thus the arm 89 may continue on while the stylus of the pickup arm assembly reproduces the record. Prior to the previous operation of the phono raph. the pin 92 projecting from the face of the cam 94 had oriented the ten-inch record stop 81 to a vertical position. At the time that the cam 86 rotates to disengagethe twelve-inch limit stop. 88, a portion of the cam surface acts to. restore the ten-inch limitstop-81 to its. original position so that this limit stop. is also moved out of the path ofthe downwardly. movingv lever arm 89.

At the end of the reproduction of the phonograph record the lever arm 89 movesinto engagement. with theswitch I95. The switch I95 is. connected in parallel with the starting switch I88 and again completes a circuit to the relay 204. Therelay. 2.94. closes itscontacts thus re-energiz-v ing thesequence operation motor-11. The cam shaft-I4 rotatesto bring the cam 94 out of engagement with the pivoted cam II3 thereby permitting a small limited movement of the slide I68. Thissmall limited movement which is permittedis brought about by the restoring sprin I'IZconnected to the end of thebell crank III. Thus the bell crank III isreturned to normal position thusslightly rotating the shaft I15 and restoring the extremities of the pickup arm assembly 41 to a vertical position where neither one of the styli is in engagement with thesurface of the phonograph record.

The cam shaft I4 rotates to move the pin 93 against the downwardly extending extremity 9| of the ten-inch record stop 81 thus movingit to avertical position. The cam 95 moves on upwardly to engage the outer extremity of the arm 89 thereby moving the extremities of the pickup arm assembly 4! outwardlyawayfrom the record.

The cam 95 continues on until it engages the spring 98.. Meanwhile thecam 86 has beenmoved so that the angularlydisplaced twelve-inch limit stop 88 has been restored to its former'position.

Thestop 88 therefore. limits the downwardmover ment of the arm 89.:

Thecam 95 acting n the spring 98moves the assembly 4! back to the "starting groove of the phonograph. record. The limit stop 88 engagin t e outer extremity of the arm 89 stops this move.-. ment; and the cam 95 continues'on to engage pivoted oamI I3 as is indicated in Figures 18 and 19. The action of the cam 95 on'the cam II3 there! fore moves the slidemechanism I68 towardthe leftethus causingthe slot-I61 to pull downwardly on the rod I 63. This-downward motion of the rod I63 shifts the driving wheels shownin Figure '7 to the position shown therein sothatthe rota-. tion of thedriving disk I5I is in the oppositedirection. The record is still supported by the arm 42 because of the actionof the spring. 8I whichis not opposed by any portion of the cam.18. The actionof the slide I68 toward the left. causes the upward projection I69 to. actuate the bell crank I1 I. This pivots the shaft I15 to move the pickup assembly. so that the other. stylus engages the opposite side of thephonograph record.. One of theouter extremities I'I3 of the bell crank I II engages the switch. I'I4 which momentarily interrupts thecircuit shown in Figure 20.

This interruption of the circuit to the sequence operation motor 'I'Ibythe. actuation of the switch I14 causes therelay 204 to be. de-energized. The

pickup arm continues to reproduce the phonograph record, the cam 95 having moved on down the surface of the pivoted cam H3. During this movement of the cam 95, the cam surface has engaged both of the limit stops 8? and 88 shown in Figure 10 torestorethem to the solid line position; The engagement of the cam surface 85 restores both these limit stops so that the arm 89 may move during reproduction of the phonograph record toward the switch I95. When the other side of the phonograph record has been reproducedthe switch I is actuated thereby again energizing the relay 294 to re-energ-ize the sequence operation motor Tl. This energization of the sequence operation motor TI causes the shaft 74 to. be rotated so that the cam 95 clears the pivotedcam I I3 to'permit the slide to be restored a short distance so. that the bell crank I'lI returns to its normal position.

In this position both styli of the pickup arm assembly 41 are freed from the surfaces of the phonograph record. The cam surface 94 thereupon engages the outer extremity of the lever89 to move the extremities of the pickup arm assembly 41 away from the outer periphery of the record. The cam surface I8 now engages the lower extremity of the arm 42 to cause the pin I44 to be withdrawn from the recess I46. The phonograph record 4| remains on thepin I44 until the disk I38 passes through the record removing wire structure 48. When this occurs the record drops into the return track 49 and rolls into therecord reject chamber 5I. At this point in thesequence of operations the phonograph mechanism is ready to supply another phonograph record from the magazine 38 provided that the magazine contains such record. If the magazine does not contain a record the switch zlll is opened and the cam 73 now moves to a position where it will open the pair of contacts I99. If both contacts I 99 and the switch 29 I are-opened; the entire operation of the phonograph ceases,

Operation for ten-inch record It may now be assumed that the records to be placed inthe phonograph magazine are ten-inch records or that the next record to be played fol-- lowing the preceding description is a ten-inch record. In general the sequence of operations is the same, .andit is believed unnecessary to repeat in detail each action. Only enough action will be given together with those actions which are changed in response to a ten-inch record.

It mayb assumed that the phonograph sequence'operation motor I1 is continuing to opcrate-so that the cam 13 moves the rod 69 to actuate the bell'crank 91 and the record selecting 'mechanism 55. A ten-inch record therefore is removed from the record magazine 39 which rolls down the record trough 56 to the record elevating trough 46. The ten-inch record in the trough 46 does not engagethe record index'member5l. If the index member 51 pre viousl y has'been actuated by a twelve-inch record, the latter half of the preceding cycle of operation of the cam shaft I4 is operated to restorethis member to its. original position since the-cam 85 inrestoring both the limit stops 8'! and 88] has caused the lower extremity on the rod 91 to be moved on the left as seen in Figure 10'. This brings a movement toward the left of the stop.l32- seen in Figure 12 so that unless the member 51 is again actuated this stop is not in position to engage the stop I33. The stop I33 19 is secured to the member 84 which supports the record trough 46.

Since the member 51 is not actuated by the ten-inch phonograph record, the cam shaft I4 drives the cam 82 against the cam follower 83 shown in Figure 12. This moves the record trough 46 upwardly to a greater extent than was the case with the twelve-inch record.

Since the member 53 has not been actuated the twelve-inch limit 88 remains in a position where it will not be engaged by the outer extremity of the arm 89. The manner in which the phonograph record is engaged and driven is the same as in the case of the twelve-inch record. The cam 94 in engaging the spring 98, however, moves the arm 89 downwardly to a greater extent until it engages the ten-inch index arm 81. This brings the extremities of the pickup arm assembly 41 in a-greater distance so that the styli are located in the proximity of the starting groove of a ten-inch record. The tilting of the assembly 41 and the manner of operation is the same as in the twelve-inch record. After one side of the record has been reproduced, the other side of the record is also reproduced if the slide button 35 is in the position originally assumed in the foregoing description of the operation for twelve-inch phonograph records.

Playing one side of the record only If it is desired to preset the operation of the phonograph for the playing of only one side of each of the records stored in the record magazine 38, this may be accomplished by actuation of the push button 35 to the position shown in Figures 1, 2, and 3. In this position the push button 35 has moved its downwardly extending portion II I so as to move the interconnecting link I 09 against one end of a bell crank I01. The bell crank I which is pivotally mounted at I08 has a curved outer extremity I which is moved into a position for subsequent engagement with the cam surface I04. The bell crank I01 at an intermediate point carries a resilient finger H2 which is moved into engagement with the pivoted cam H3.

Assuming that a phonograph record has been supplied to the driving mechanism, the cam 94 moves on to engage the pivoted cam II3 thus moving the slide I68 toward the right as indicated by Figures 16 and 17. This causes the pickup of the assembly 41 to reproduce one side of the phonograph record as indicated in Figure 1%. After the record has been reproduced on that side, the switch I95 is actuated to cause further movement of the cam shaft 14. At this time, however, the cam 94 clears the cam H3 and the cam surface I94 engages the outer extremity I05 of the bell crank I01 which deflects this cam in the manner illustrated in Figure 11. The cam thus being deflected fails to engage the outer extremity of the arm 89 and also fails to engage the pivoted cam surface H3. The result is that the bell crank lever III is not again actuated so as to engage the switch I14. The sequence operation motor TI therefore continues to rotate until the cam surface 95 engages the outer extremity of the arm 89 to move the tone arms 41 away from the phonograph record. When this occurs the cam shaft has rotated sufiiciently to bring into engagement the cam 18 with the rod 42 so as to strip the phonograph record from the pin I44 and to cause it to drop into the return track 49. This sequence of operations is brought about for each record so that only one side of each record is played.

' in the Playing of individual records The phonograph may be operated so as to play individual records which has commonly been called by the trade manual operation of the automatic phonograph. A single record may be placed in the record magazine 38 for playing either one side or both sides of the record dependent upon the predetermination of the operation as controlled by the setting of the slide knob 35. If only one side of the record is to be played, the control knob 35 is moved to the position shown in Figures 2 and 3. If it is desired to play both sides of the record the control knob 35 is moved to the other end of the slot 36 escutcheon 31. Having determined whether one side or both sides of the record are to be played, the push button 34 is actuated. Where the phonograph record is placed in the trough or magazine 38, the record trough switch 20I is closed by the Weight of the record so that actuation of the push button to close the switch I88 will bring about one cycle of operation of the mechanism of the phonograph. The record will be lifted by the mechanism 55 into the trough 56 from which it will pass on to the trough elevator 46 for subsequent positioning on the phonograph record rotating mechanism and reproduction by the tone arm. The operation of the mechanism in this respect is the same as the operation previously described for a series of records in the automatic operation of the phonograph.

If desired individual records may be played by placing the record directly into the trough 56 so that the record moves on down to the record elevator 46. When the record is in the elevator 46, the push button 34 may be actuated. The push button 34 as may be seen from the circuit diagram of Figure 20 closes two single throw normally open contact switches I88 and I90. switch I88 by itself is eifective to initiate a cycle of operation of the phonograph when the switch in the trough 56 so as to move on down to the elevator 46, the switch I90 is closed by the push button 34. The switch I90 is in parallel with the switches MI and I99. The closing of the switch I 90 initiates operation of the phonograph so that the cam actuated switch I99 is subsequently closed to permit elevation of the record in the record trough 46, and reproduction of the record.
